The Lowdown
Alright, let’s break this down for the next couple of weeks. Karramarro is an advanced point break that doesn’t fire all that often, so when it does, you need to be ready. The water is sitting at 24°, which is much warmer than normal for this time of year – a nice bonus if you’re getting in.
The first few days, from Tuesday 25th through Thursday 27th, are flat. The energy is tiny (10 to 61) – barely anything. Not worth wetting a suit.
Friday morning 28th is where it starts to kick. A clean 1.7m swell from the WNW (energy 365) with a 9 mph offshore from the SSW – that’s going to have some proper shape. It’s a bit big for anyone not comfortable in overhead surf, but for the advanced crew, that’s the first real window.
Saturday morning 29th is glassy with a solid 1.5m NW swell (energy 349). That’s clean and punchy, and with the glass-off, it’ll be a treat if you’re out early. The afternoon goes onshore and messy.
Sunday 30th through Monday 31st sees the swell dropping and the winds turning. Ordinary stuff.
The standout of the whole run lands on Tuesday morning 1st September. Glassy conditions with a 1.7m NW groundswell (energy 663) and an 11-second period. That’s proper, lined-up waves with good energy – clean and powerful. Circle this one. The afternoon goes cross-on, so hit the morning.
Wednesday 2nd morning is also glassy with 1.5m NW swell (energy 383) – another good session, just a step down.
Thursday 3rd and Friday 4th are ordinary with onshore winds and smaller surf.
Saturday 5th is small and weak, Sunday 6th picks up a bit (1.3m, energy 499) but gets cross-off winds – surfable but not a standout.
Now, look at Tuesday 8th September. That’s a big one – 3.5m of WNW swell (energy 3126) with glassy conditions. That’s a very heavy, expert-only day. The energy is enormous. If you’re not properly experienced, stay on the beach. Wednesday 9th still has size (1.8m) but the winds are less friendly.
For the whole run, the absolute best sessions are Friday 28th morning, Saturday 29th morning, and Tuesday 1st September morning – with Tuesday 1st being the pick for clean, quality waves.

Information about the Karramarro Surf forecast
The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
